DEVICE FOR ROTATING- EGGS INCUBATORS.

To all whomit may concern.'

Be it known that I, DAVID ABRAM CALLA- WAY, a citizen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented a new and useful Im rovement in Devices for Rotating Eggs in ncubators, of which the following is a specification.

My invention relates to devices for rotating eggs in incubatore in which a'rectangular frame composed of end pieces in two parts hinged together and connected by felt covered rods, adapted to hold eggs while being rotated, the eggs being held outwardly against the framework by a felt covered cylinder suspended ,in the middle of. the framework at its ends; and the objects of my'in within an incubator by means ofl motor` power; second, to provide such rotating means in such form that one or more rotating devices may be operated in an incubator by one motor; third, to provide such rotating device to be applied to any ordinary incubator now in use without altering the heating or moisture a plying apparatus, or any part of the same; ourth, to provide such a rotating device that provides for proper ventilation ofthe eggs while being rotated and fifth, to provide such rotating device to minimize the attention necessary to be given to the eggs during incubation. I attain these objects by the mechanisms illustrated in the accompanying drawings, in which Figure 1 is a perspective view, 'in partial broken section, apart from an incubator or motor, of my invention, with the eggs shown in proper position to be rotated; Fig. 2 is a conventional elevation of one end of my invention showing the framework opened for' iilling with eggs or to remove 'them Fig. 3 is a side elevation of a portion of the end pieces and the felt covered cylinder in broken section, showing manner of applying the latter, and the trunnions on which the device rotates Fig. 4 is an end elevation of two rotating devices as they will appear mounted on bearings to be rotated by sprocket chain. Fig. 5 is a cross sectional view of rod 6, showing felt covering 6a.

Similar numbers refer to similar parts throughout the several views.

The frame shown in Fig. 1 is composed of two rectangulaiframes hinged together. The lower frame is composed of end pieces 1 that are held together by rods -,which may be covered with a soft material, such as felt. The upper frame is com osed of end ieces 1 a that are held together y rods 6. he two frames are hinged at 2 and when closed together as in Fig. 1, are held by hook 3, which is pivotally attached to end pieces laby rivets 4 and engages end pieces 1 at pins 5. To fill with eggs the frame is o and the eggs 9 lai in on rods 6, whereupon the felt'covered cylinder 10 is placed first on pivot 7 a of trunnion 7, which carries sprocket wheel 8, and trunnion 7 b is pulled outwardly until the cylinder 10 is pro erly centered, when pivot 7 enters a suitable hole in cylinder 10, and is held securely by spring 11, which is held in housing 12. 4The cylinder 10 will hold the eggs so they will not iall out while the frame is beinlg1 closed and hooked by hook 3, whereupon t e eggs 9 are heldby cylinder 10 out against rods .6. The frame t us filled with eggs is set in suitable bearings 14, in which as many rotating devices may be operated by one motor as the space in the incubator will accommodate. To facilitate in spacing the bearings apart and to keep them in line and from moving out of proper alinement, the base of the bearing stands 14 are provided with a dovetail connection. The ton ue 14b of end 14d enters a notch 14c of en( 14, each base having a tongue on one end and a notch on the other. By means of this tongue and notch arrangement it may be seen that either an upward or sidewise movement of the rearmost stand will be held by the next stand therefore this manner of connection tends to produce a solid base when the tongues and notches are properly fitted. The chain 13 engages the sprocket wheel 8 as shown in Fig. 4, and a sprocket wheel 16 on any suitable motor 15, or clock mechanism, which is constructed to move the chain slowly in such manner that the rotating devices will be turned once around in twenty-four hours, or as many times around as desired in a given time. It may be seen that the arrangement of these mechanisms provides for rotating one or more of my devices at one time by one vsource ofcpower; and that one or more of the rotating evices may be applied to any ordinary incubator in the heated portion usually occu ied by egg trays and that the eggs will be t ioroughly ventilated by passing circuitously through thc air in thc heated chamber of the incubator and that the eggs need no p heating or moisture supplying devices there-. gin, or any part of the incubator; and is particularly useful in saving time heretofore ernvploy'ed in turning the eggs, and useful in producing strong, healthy fowls, since the rotation of the eggs, being continuous, brings the life giving parts of the eggs into complete contact With each other. l

Not confining myself to the kind of motor for furnishing power to rotate my invention, nor to the manner of connecting the same to it by sprocket chain, gears, or by attaching a motor to each rotating device on trunnions 7.

What I claim as new and desire to secure by Letters Patent is- 1. In a contrivance of the character described for rotating eggs in an incubator, a rectangular frame, composed of felt covered rods and two end pieces connected therewith, each end piece composed of two parts hinged together whereby said frame may be o ened and closed, a trunnion on each 0f suc end pieces, a sprocket wheel on one of said trunnions, a removable cushioned cylinder centrally disposed within said frame adapted to hocld eggs outwardly against said cushioned ro s.

2. In a contrivance of the character described for rotating eggs in an incubator, a combination of an egg containing frame having trunnions on each end, a s rocket wheel on one of said trunnions, an a plurality of bearing stands s aced apart having therein bearings adapte to receive operatively said trunnions and carrying a plurality of said egg containing frames, bases on said bearing stands, each of said bases providedv with a notch in one end and a tongue in the other and adapted to interengage to securel of egg containing frames, all substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of LYMAN I. HENRY, f S. MAUDE ENGLE.
